The deal could be completed as soon as Saturday and will include a vesting option for a third year, according to Brown.

KRIS-TV in Corpus Christi, Texas, reported Friday night the sides had agreed on a three-year deal worth $18 million. Adams was born in Corpus Christi but went to high school in nearby Sinton.

Jason Adams, Mike’s brother, reportedly posted on his Facebook page that the reliever was joining the Phillies.

Adams, 34, has been one of the top setup men in the game over the past five seasons. Last season, he posted a 3.27 ERA in 61 games for the Texas Rangers and was fifth in the American League with 27 holds. He struck out 45 batters in 52 1/3 innings.

With the Phillies, Adams will presumably work the eighth inning as the bridge to closer Jonathan Papelbon. One of Philadelphia’s downfalls in 2012 was the club’s inability at times to get the ball to Papelbon with a lead.

Adams underwent surgery in October for thoracic outlet syndrome, a condition in which a rib bone presses against a nerve, causing pain and numbness in the arm. Adams is expected to be ready for spring training, MLB.com reported in October.
